Question

안녕하세요. 강의 잘 듣고 있습니다. 다름이 아니라 실행하실 때, dev 프로파일이 아닌, 기본 으로 하신걸까요..? 강의에서는 dev설정에서는 8081포트로 되어 있어서요. 그리고 로그가 잘 나오는데, 뒤에 이런 에러가 나오는데 어찌 해야 되는지 잘 모르겠습니다. 감사합니다. feign.codec.DecodeException: Type definition

Bruce Han · Answer

retryer() 하고 HealthCheckController.checkHealth() 부분을 다시 보시겠어요? 저는 HealthCheckResponseDto에 @Getter와 @Builder만 넣어도 잘 됩니다 HealthFeignTestController도 다시 한 번 확인해보시면 좋을 듯합니다

구파고 · Answer

안녕하세요 오류메세지를 보면 http body에 HealthCheckResponseDto를 담아서 반환해줄 때 오류가 나고 있습니다. Cannot construct instance of com.app.springapiapp.api.health.dto.HealthCheckResponseDto (no Creators, like default constructor, exist): cannot deserialize from Object value (no delegate- or property-based Creator) 강의에서 HealthCheckResponseDto에 @Builder 어노테이션과 @Getter 어노테이션을 붙여 두었는데 해당 어노테이션도 클래스위에 선언을 해주셨을까요?
